taskd: fix static linking issue with libuuid/libintl

libuuid depends on libintl in specific scenarios, but since taskd wasn't
using pkg-config to detect libuuid, this dependency on libintl was not
taken into account. This commit adds a patch to taskd that uses
pkg-config to detect libuuid.

Fixes:
